Appium之编写H5应用测试脚本（切换到Webview）

App使用H5编写，默认方式找不到元素。启动后获取所有上下文，找到webivew_xxxx的，然后进行切换。

源码：

 package MyAppium;
 
 import io.appium.java_client.android.AndroidDriver;
 import org.openqa.selenium.By;
 import org.openqa.selenium.WebElement;
 import org.openqa.selenium.remote.DesiredCapabilities;
 
 import java.net.MalformedURLException;
 import java.net.URL;
 import java.util.Set;
